IPC: H03M1/82
Filed: 1981-08-11
Abstract: This invention relates to a method of converting a digital signal into an analog signal and a digital-to-analog converter therefor. In the invention, a digital signal having varying pulse width values is converted into a first pulse width signal, with each pulse varying in its pulse width in response to its respective data values and with the center of each pulse width being at a fixed time position within a respective sampling period, while a complement of the digital signal is converted into a second pulse width signal with each pulse varying in its pulse width in response to its respective data value and relative to said center of each respective pulse width. The first and second pulse width signals, after one of them is inverted, are mixed and pass through a smoothing filter to demodulate the digital signal into the analog signal.

Abstract: A heating unit (1) for a hotplate has an outer heater (3) and an inner heater (4), which is located in said outer heater (3), for essentially separately heating in each case one associated area region (13, 14) of the overall heating surface (2). The two heaters (3, 4) can be controlled differently and, in this case, the power supplied, for example, is distributed to the two heaters (3, 4) such that it switches over periodically and alternates without any gap in very short, but variable time intervals. The switching-over takes place as the alternating-current characteristic passes through its zero line. In consequence, any desired power distribution can be achieved (without influencing a click rate) on at least two area regions (13, 14) of the same heating surface (2), and a high efficiency is achieved as well as matching to the respective heat consumption, with the aid of relatively simple control means (10). <IMAGE>

Abstract: Disclosed is a process for treating manganese dioxide containing ion-exchangeable cations by replacing the ion-exchangeable cations present in the manganese dioxide with lithium by a process comprising first replacing ion-exchangeable cations present in the manganese dioxide with hydrogen. This readily is accomplished by slurrying the manganese dioxide in an aqueous acid solution. The resulting acidic manganese dioxide then is neutralized with a basic solution of a lithium containing compound, such as lithium hydroxide. This neutralization step serves to accomplish replacement of the previously introduced hydrogen, by ion-exchange, with lithium. The manganese dioxide then is washed with water, dried, and heat-treated at an elevated temperature, in conventional manner, to convert the gamma manganese dioxide to a mixture of the gamma and beta forms, which then is used as the active cathodic component in an electrochemical cell.

Abstract: A wrap-around bottle carrier wherein the bottle heel cutouts at the ends of the carrier are spaced from the ends a greater distance than normal to increase the strength of the carrier at this area of stress. To permit this arrangement to be used, the shape of the outer or end cutouts is altered by connecting the top of the cutout to the vertical inner side portion of the cutout by a straight cut rather than by the usual curved cut. This allows the edges of the end cutouts to contact the bottles when the carrier is lifted even though, due to the change in dimensions of the end cutouts, the end cutouts are not symmetrically arranged with respect to the centerline of their associated bottles.
